Combustion of Polymeric Materials
Matti Elomaa,Liisa Sarvaranta,Esko Mikkola,Raija Kallonen,Antti Zitting,C. Zevenhoven,Mikko Hupa +6 more
TL;DR: Polymeric materials can be natural as wood, proteins and cotton or synthetic such as most of the plastics and the elastomers Chemically they are composed of one or more polymers and can contain other types of compounds like mineral fillers or dyes as discussed by the authors.

Analysis by pyrolysis/gas chromatography/mass spectrometry of glass fibre/vinylester thermal degradation products
N. Regnier,B. Mortaigne +1 more
TL;DR: In this paper, thermal degradation of vinylester materials crosslinked with styrene by thermogravimetric analysis (TGA) and the identification of emission products by pyrolysis/chromatography/mass spectrometry (PY/GC/MS) demonstrates that thermal degradation begins with a polystyrene chain depolymerization.

Direct Examination of the Degradation of High Polymers by Gas Chromatography
R. S. Lehrle,J. C. Robb +1 more
TL;DR: In this article, the degradation products of high polymers are characterized by gas chromatography as they are formed, and a pulse of degradation products in the chromatographic apparatus is generated so that the products are swept into the column with the minimum delay and disturbance.
Journal ArticleDOI
Pyrolysis-gas-liquid-chromatography utilised for a kinetic study of the mechanisms of initiation and termination in the thermal degradation of polystyrene
TL;DR: In this paper, the pyrolysis mechanism involves both initiation at the chain-ends and initiation by random scission, and the activation energies for scission and end-initiation for both types of sample were analyzed.
Journal ArticleDOI
An improved (“thermocouple-feedback”) pyrolysis-GLC technique and its application to study polyacrylonitrile degradation kinetics
TL;DR: An improved pyolysis-GLC unit has been designed in which a micro-thermocouple is spotwelded to the pyrolysis filament, and the thermocouple output is used as a feedback signal to control the power supply to the filament.

Kinetic measurements by micropyrolysis-GLC: Thermal degradation of polymethylmethacrylate possessing lauryl-mercaptyl end groups
G. Bagby,Roy S. Lehrle,J.C. Robb +2 more
TL;DR: In this paper, a sample of polymethylmethacrylate possessing lauryl-mercaptyl end groups has been fractionated by gel permeation chromatography, and measurements of the thermal degradation of the fractions have been performed by micro-pyrolysis-gas-liquid-chromatography.
